Erratum: Single spin asymmetry through QCD instantons [Phys. Rev. D86, 014033 (2012)]

Abstract

We correct Eq. (10) for deep inelastic scattering (DIS) through QCD instantons and its longitudinal as well as transverse projections. For the single spin asymmetries (SSA) in DIS with longitudinal polarizations, the corrected results fit better the reported data, while for the transversely polarized protons the results are larger than the experimentally reported data.

Fragmentation contribution to the transverse single-spin asymmetry in proton–proton collisions

“…Various processes have been analyzed over the last two decades using this methodology -see [12][13][14][15][16][17][18][19][20][21][22][23][24][25] for some specific examples. (We also mention that other mechanisms have been proposed to explain large SSAs [26][27][28][29].) Furthermore, the collinear twist-3 formalism has been used to describe the double-spin observable A LT in different reactions with one large scale [30][31][32][33][34][35][36][37].…”

Spin physics through QCD instantons

“…Perturbative QCD does not support the T -odd contributions, which are usually parametrized in the initial state (Sivers effect) [20,21] or the final state (Collins effect) [22,23]. Non-perturbative QCD with instantons allow for large spin asymmetries as discussed by Kochelev and others [24][25][26][27]. In [24] a particularly large Pauli form factor was noted, with an important contribution to the Single Spin Asymmetry (SSA) in polarized proton on proton scattering.…”

“…In addition to the un-binned PL analysis, a χ 2 -test following [23] and a Lomb-Scargle (LS) periodogram [24] were carried out using binned data. For both tests, a strong binning dependence of the result is observed.…”
